/6 198 rods needed badly

lol i cant compare a F1 for an example but your going to throw out prostock? And to tell you the truth i think you pointed out a big point by accident! Those short deck, short rod motors get torn down very often because they blow up or wear out past spec. No so with F1...

everyone will agree that a high rod ratio lowers mechanical friction... and if you read and find it out for yourself the dwell benifit can be big ESPECIALLY on our poor breathing NA slant six...

I never said anything about rod-length ratios on Pro Stock motors... just that David Reher builds a lot or Pro Stock motors. And, he does... but alludes to his reasoning RE: the Small-Blocks, he and partner (R.I.P.) Buddy Morrison built back in the day... when they always worked toward a 1.9:1 rod/stroke ratio. THAT is what he was referring to when he contended that rod-length is unimportant to the output, not in Pro Stock... He just threw in the low-deck, short-rod P/S motors they currently build, to prove a point.

And yes,a F-1 engine will go a long way with a 2.7:1 rod/stroke ratio. Why wouldn't it; the angularity is minimal...
